These pillows are pretty heavy; I knew I'd like them. They're pretty solid and perfect for someone who sleeps on their side. The odd thing about the pillows is my husband is no longer snoring and tossing and turning. For years I have listened to his irregular and noisy snores, holding his breath, tossing and turning, and hitting and kicking. I've succumbed to wearing earplugs at night. Call it an odd coincidence, but ever since getting the pillows Thursday, we have had extremely peaceful nights of sleep with no earplugs. I guess the firmness stretches his neck so his air passage isn't blocked. Whatever the reason, I highly recommend these and wish I would have thought of them 19 years ago!!
